Houston, We Have Lift-Off

Marquette is feeding goldfish in the new aquaponic system at Houston Elementary School of DCPS.

We constructed a grow-trough light enough to sit on the walls of the 75-gallon fish tank.

Water is pumped from the fish tank up to one end of the trough, and drains back into the fish tank from the other side through a bell-siphon. We have some parsley and green onions planted up there to start.
